Canonicalize various financial data file formats to OFX 2 (a.k.a XML)

Canonicalize various financial data file formats to OFX 2 (a.k.a XML)

Fixofx is a library and an utility to canonicalizes various financial data file formats to OFX 2, which is an XML format and hence a lot easier for other code to deal with. It recognizes OFX 1.x, OFX 2.x, QFX, QIF, and OFC.

Pipe a data file to ofxfix.py, or specify an input file with the -f flag, and if the file is successfully parsed, an OFX 2 file with equivalent data will be output.

Various parts of Fixofx go through contortions to try to interpret ambiguous or malformed data, both of which are very common when importing bank data files. QIF, in particular, is an extremely irregular file format, and Fixofx makes best efforts but will not cover all cases. Also, some international formats are recognized and interpreted, such as British versus US date formats, but more work could be done on this.

Sometimes a data file will not contain information that is important for OFX – for instance, neither OFC nor QIF include the OFX “FID” and “ORG” fields. Other times, the data format will include this data, but inconsistently, such as QIF’s account type, which can be ambiguous or absent. In these cases you can ask the user to provide hints to Fixofx, and convey those hints via command-line options (see Command line operation, below).

The Fixofx project also includes ofxfake.py, a utility script to generate fake OFX files for testing purposes.

Installation

pip install fixofx

This package only works on Python 3+.

Tests

A partial test suite is included. Run it as follows:

git clone https://github.com/henriquebastos/fixofx.git
pip install -r requirements-dev.txt
py.test

Command line operation

The simplest invocation of the script is:

./ofxfix.py -f <path-to-data-file.fmt>

You can also pipe a data file to standard input – that is, this invocation is equivalent to the above:

./ofxfix.py < <path-to-data-file.fmt>

There are several command line options, as follows:

-h, --help                     show this help message and exit
-d, --debug                    spit out gobs of debugging output during parse
-v, --verbose                  be more talkative, social, outgoing
-t, --type                     print input file type and exit
-f FILENAME, --file=FILENAME   source file to convert (writes to STDOUT)
--fid=FID                      (OFC/QIF only) FID to use in output
--org=ORG                      (OFC/QIF only) ORG to use in output
--curdef=CURDEF                (OFC/QIF only) Currency identifier to use in output
--lang=LANG                    (OFC/QIF only) Language identifier to use in output
--bankid=BANKID                (QIF only) Routing number to use in output
--accttype=ACCTTYPE            (QIF only) Account type to use in output
--acctid=ACCTID                (QIF only) Account number to use in output
--balance=BALANCE              (QIF only) Account balance to use in output
--dayfirst                     (QIF only) Parse dates day first (UK format)

Debugging

If you find a data file fixofx can’t parse, try running with the -v flag, and if that doesn’t help (which it probably won’t), try the -d flag, too.

Most of the time a failed parse is due to a malformed data file. QIF, especially, is damn near undocumented, and different banks just seem to make stuff up about how they think it should work. And they don’t talk to each other about their crazy QIF theories, either. So that’s bad.

If you think the script is basically working (e.g., tests pass) but a parse is failing, the best thing to do is to just look at the data file and see how it is different from other examples you’ve seen. Post a cleaned-up (sensitive data removed) snippet as a gist if you want someone else to help. Usually a difference will jump out at you after a while if you’re familiar with the format.

ofxfake.py

The ofxfake.py script generates real-ish-seeming OFX for testing and demo purposes. You can generate a few fake OFX files using the script, and upload them to Wesabe to try it out or demonstrate it without showing your real account data to anyone.

The script uses some real demographic data to make the fake transactions it lists look real, but otherwise it isn’t at all sophisticated. It will randomly choose to generate a checking or credit card statement and has no options.

Contributing

Contributions to Fixofx are welcome. Please add tests for your contribution and make sure all tests pass before sending a pull request. Here are some ideas for things to do:

  • fakeofx could use some command line options and a little more control over the output. (EASY)
  • The OFX parser class has some ugly regular expression hacks added to deal with a variety of malformed OFX inputs. Each new regex makes things slower and makes the baby jwz cry. Find a better path. (EASY)
  • Fill in missing tests, especially in QIF conversion. (MEDIUM)
  • Fixofx currently converts QIF to OFX/1, and then OFX/1 to OFX/2, which is totally crazy-pants and makes everything ungodly slow. Go straight from QIF to OFX/2 instead. (MEDIUM)
  • Some people would be happy if Fixofx accepted a bunch of input formats (as it does) and had options for outputing any of those formats, too (right now OFX/2 output is the only option). Basically, convert everything to an internal representation and then output whatever kind of document the user wants. (MEDIUM)
  • The date format parsing could be a lot more intelligent, using windows of transactions to guess the date format instead of requiring at least one unambiguous date. (MEDIUM)
  • There is the start of a CSV converter in ofxtools. This has to be one of the most-requested Wesabe features evar. Have at it. (HARD)
